MECHANICAL GOLF INSTRUCTOR AND EXERCISER.

Application filed December 29, 1926. Serial No. 157,751.

My invention has reference to a mechanical golf instructor andexerciser,and relates to certain improvements in a'device of that type which isset out in my former application for Letters Patent of the United Statestiled Oct. 25, 1926, and numbered 14l3,977. Said former applicationembodied a track of approximately circular form, serving as a guide fora frictionless traveller to which was attached the end of a golf club orstick used in practice. Associated with the traveller was mechanism forcontrolling the axial movement of the 'clubin its trip round the track,compelling the same to follow the natural movement of the club in makinga stroke. Included therewith was a channel in the face of the track andaroller operat-' ing therein, by which the controlling mechanism wasactuated.

In the present invention the channel is replaced by a track onthe faceoft-he rail.

forming the main track, upon the'edges of which travels a pair ofrollers connected with the control mechanism, and imparting movementthereto. construction and operation of the device is the same as in saidformer invention, except that the traveller rides on the edges of thetrack instead of on its faces.

The particular construction, arrangement, and operation of the variousparts of the invention will be more thoroughly understood from thefollowing specification, reference being bad to the accompanyingdrawings, in which;

Fig. 1 shows a fragment of a track upon which the traveller operates,with the traveller in position thereon.

Fig. 2 is a cross-section on the broken line 2-2 of Fig. 1.

The reference number 1 indicates a section of track,.the main part ofwhich is understood to be of a suitable shape and size to enable aplayer to stand in a central posi tion and describe a stroke with a golfstick, the track serving as a guide therefor. On one of the faces of thetrack 1 is a track 2, extending from one end to the other thereof.Slidable on the track 1 is a frame 3, by means of rollers 4: at thecorners thereof, and grooved to conform to the semi-circular formationof the edges of the track. In the upper part of the frame, which runs onthe inner side of the track, is a bearing 5, in

In other respects thewhich is journalled a shaft 6, on the upper end ofwhich is a yoke 7,.connected by a swivel pin 8 with the yoke 9 on theend of a stick 10. This'stick is shown broken away, and would be ofsuitable length and shape for use as a golf club.

Projected. fromthe bearing 5 is a bracket 1, supporting a bearing 12, inwhich is journailed the outer end of a shaft 13, the other end of saidshaft being supportedin a part of the frame 3. is a .sleeve 14, to whichis fixed a bevel-gear wheel 14, in engagement with a bevel-gear wheel 15on, the lower end of the shaft 6. A gear-wheel 16 is also fixed to thesleeve 1 1, and pivoted on the frame 3 as at a is an arm 17, on one endof which is a segment gear 17, the teeth of which are in mesh with theteeth of the wheel 16. In the other end of'the arm 17 is a pin 19, onwhich is pivoted a link20 in the opposite ends of which are rollers 21and 22, which bear against opposite edges of the track 2. V

During a large part-of its course the track 2 is in parallel relationwith the track 1, near one edge or other of said main track, but inanother part it crosses from one side to the other, as indicated inFig. 1. This results in a rocking movement of the arm 1'? and segmentgear 18, imparting rotation to the shaft 13, which is communicatedthrough. the gearing 14 and 15 to the shaft 6 and stick 10 connectedtherewith. This movement is suflicient to give to the stick a halfrotation, and the arrangement of the track 2 is such that the movementbegins at the right hand side of the player and ends at the oppositeside. In the case of the use of an actual golf club this would have theefi'ect of turning the shaft from a position with the face of the clubto the front to a position with the face of the club to the rear,following the natural course thereof. It will be observed that the handsof the player will 23, by the release of which the link and rollers canbe removed. This will permit free movement of the stick 10, in case itis desired to use the same without hindrance 'b' the earin and camtrack.

suitable track provided with a cam-track on one of its faces, a frameprovided with rollers operable on said first-named track, an arm carriedby said frame and provided with a follower for said cam-track, a pivotalstick connection in said frame, and means for imparting the movement ofsaid arm to said pivotal connection, to suitably rotate the same.

In a device of the class described, a suitable track provided with acam-track on one of its faces, a frame provided with rollers operable onthe edges of said first named track, and provided with a pivotalconnection, an arm rockingly mounted on said frame, gearing connectingsaid arm with said pivotal connection, a link pivoted to the free end ofsaid arm, and rollers on the ends of said link bearing against oppositesides of said cam-track.

In a device of the class described, a suitable track and canrtrack onone of the faces thereof, a frame movable on said firstnamed track andpivotal connection mounted thereon, an arm rockingly mounted on saidframe, means for imparting the rocking movement of said arm to saidpivotal connection, to rotate the same, and a follower for saidcam-track detachably connected with said arm.

t. In a device of the class described, a suitable track and cam-trackthereon, .a frameslidable on said first-named track, a pivot mounted insaid frame and stick-coupling connected therewith, an arm rockinglymounted in said frame, gearing connecting said arm with said pivot,alink pivoted to said arm and detachable therefrom, and rollers carriedby the ends of said link, engaging the sides of said cam-track.

In a device of-the class described, a suitable track and cam-track onthe face thereof, a frame slidable on said track, a pivot supported insaid frame and coupling on the inner end thereof, a bevelear wheel onthe outer end of said pivot, a bevel gear wheel rotatably mounted and inineshwith said first-named bevel-gear wheel, a gear pinion rotatablewith said second-named bevel-gear wheel, an arm pivoted in said frame,and provided on one of its ends with a segment gear in mesh with saidgear pinion, and a follower for said cam-track on the other end of saidarm.

In testimony whereof I aflix my signature.

JOHN HANSEN.
